> Solar Panel Calculator

This solar panel calculator will, given the Watt rating of a solar panel, the panel dimensions and number of solar panel units to be installed calculate for you the total solar power you can expect and the roof space taken up. It will also tell you the rated voltage and ampage, useful for correctly sizing an inverter or regulator, and for making sure you have the right ampage cable.

Values for the Solar Panel

Rated power of the solar panel (W):50 w is normal powerVoltage:Usually 12 or 24 voltsWidth (mm):Height (mm):Number of Panels:Wiring Format:

Remember, the values calculated here for solar energy production should be taken as a rough guide, it does not take into account other effects (like cloud cover, transmissions losses, building and tree shading, etc).
